LUBRICALTING SYSTEM Specification of Letters Patent.

Patented June 11, 1907.

struct a lubricating system that lubricant stored under pressure may be delivered at the several points desired, which may be at a considerable distance from the storage tank, and that the feeding of such lubricant from the tank through any one, of a series of delivery pipes may be controlled from a point,

or oints, which are distant from such tank.,

he object of the invention is also to provide a new and improved lubricating system by means of which lubricant may be applied to thefguard rails, of a trackover which the car, or engine, carrying the lubricating system is, or may be traveling.

The object of the invention is also to more positively apply lubricant to railway rails, or

to other parts to be lubricated.

Further Obj ects of the invention will appear from the description and claims. 1

The invention also consists in such other novel features of construction and combination of parts as'shall' hereinafter be more fuly described and pointed out in the claims.

igure 1, represents a vertical cross sectional view of a railway truck carrying the improved lubricating system, the storage tank being shown in section, and the delivery pipes being illustrated as extending, a prommately, to the rails on which the w eels of the truck are intended to travel. Fig: 2, re resents a side elevation of portions .of t e 'same. Fig. 3, represents a sectional view of the tank, taken at right angles to that shown in Fig. 1, on line 3.-3 of said figure, to more clearly disclose the construction of the tank and its valves, as also the means for con- Fig. 4, represents asecthe lubricant may be applied to the main rail. Fig. 5, represents a dlagrammatical view of the device as referably designed for use in connection wit shaft, or other bearings, and

' illustrating the preferred means of controlling the feed valves from points distant from the tank.

Similar numbers of reference designate corres onding partsthroughout. As i lustrated in the drawings, 6, and 7-7 represent portions of a railway, or other truck or carriage, furnished with wheels 8 which are adapted to run on any usual rails as A and Bu These rails are herein shown as having treads c and d, and guards e and f, approximately as a cross section of a bridge track, or other track, both rails of which are provided with guard rails: It is however evident that, on a curve, one or the other'of the guard flanges might preferably be omitted or the space between said flange and the main rail should be so proportioned to the radius of the curve that the flanges of the wheels traveling thereon would not bind or cramp.

To the members 6 and 77 of the' truck is secured a tank 10 of substantial construction and having the partition 1 1 to form the lubricant containing chamber 12 in such tank, and.

the cover 13 which closes the compartment 14, adapted to contain the valve mechanism. From the partition 11 extend the" brackets 15-.15 and 16-16, below which are formed, in the partition and its projection, the channels 17 and 18; connecting with these Chan nels are the perforated branch fittings 19 and 20 havin valve seats in their upper ends, and in t ese valve seats rest the conical valves as 21, the stems 22 and 23 of which work through perforations in the walls of the respeptive channels 17 and 18, and through perforations in the brackets 16'16 the upper ends of the valve stems being furnished with the metal plates 24 and 25, and the stems being normally -depressed by the springs 26 and 2'1 bearing against the lower surfaces of said brackets and working against the pins 28 and 29 of the respective valve stems. t

From the brackets 15-15 depend the magnets 30 and '31 the coils of which are respectively connected by the electric connections wand m and through the electricbattery 32-, or other source of electric en- .ergy, with the plates 33 and 34 and with thecompartment 12 through the pipe 36 which is provided with any usual form of valve as 37 to prevent the flow of lubricant back into said pipe.

Pressure is supplied to the compartment 12 through the pipe 38 which is connected with any air or other pressure supply, asthe pump 39, located at some point convenient for operation; this pipe 38 is also furnishedwith a valve of any usual construction, as that indicated in dotted lines of Fig. 1 of the drawings and designated by thenumeral 40.

To the branches of the fitting 19 are connected the pipes 41 and 42, while to the branches of the fitting 20 are connected the pipes 43 and 44 these pipes extend outward, approximately to the line of the wheels, and then downward, the pipes 41 and 44 having their ends positioned to deliver lubricant to the inner edges of the guard flanges e and f.

The ends of the pipes 42 and 43 are connected, by the flexible tubes 45 and 46 with channels as 47 of the respective shoes 48 and 49; these shoes having the curved under surfaces, shown in edge view in Fig. 2, and the flanges 50 and 51, Figs. 1 and 4, by which the shoes are positioned on the rails. Extending upward from the shoes are arms 52 and 53 which work through guides in the brackets 54 and 55, secured to'some stationary part of the mechanism, said arms being depressed by the springs 56 and 57 working between the respective brackets and the cross pins with which the arms 52 and 53 are furnished.

As the shoes 48 and 49 are normally elevated, out of contact with the rails A and B, connections 58 and 59 are provided for the arms 52 and 53 whereby these arms and their shoes may be -raised against the action of the springs; the connections 58 and 59 extend to any convenient point on the car, or

engine, from which said connections may be readily handled.

When the compartment 10 is supplied with oil, or any'other fluid or semi fluid lubricant, and pressure is applied thereto by means of the pump 39, or-other pressure system, the device is in condition for use; al-' though for some purposes andfor use with a comparatively readily flowing lubricant, the pressure may be omitted.

.As the plates 24 and 25, of the valve stems 22 and 23, are formed of metal, or material, adapted to be attracted by the cores of the magnets 30 and 31 when such cores are energized by electric current passing through the surrounding coils, it is evident that upon the completion of either of the circuits m g, or; a;"y, by the swinging of the switch 35 into electrical contact with either of the plates 33 or 34 the corresponding valve stem 22 or 23 will be moved. against the action .of vits spring and, the valve will be moved from its seat, as 21, thus permitting the lubricant to pass through one or the other of the fittings esaeaa and 42, or 43 and 44 as the case maybe, thus delivering lubricant through the channel 47 of the shoe, 48 or 49, to the'inner edge of one of the main rails, as c, and, bythe wiping action of the shoe, distributing the lubricant on said rail, while through the other of said pair to the pipes connected thereof pipes lubricant is delivered to the guard flange as f of the other rail. After passing the portion of the track referred to, the switch 35 is brought to the position shown in Fig. 1 of the drawings, to break the circuit and to release the plate 24 or 25, thus permitting the particular valve stem to be moved downward by its spring to close the valve. At the same time the connection 58 or 59 is drawn upward to raise the shoe 48 or 49 out of contact with the track, the flexible connections between the shoes and their supply pipes permitting this movement.

In illustrating the modified use of the mechanism in Fig. 5 of the drawings, 1 have shown, and preferably use, a tank of the same construction shown in Figs. 1 and 3. The circuits ac-y of the res ective magnets 30 and 31 however are pref drably provided with independent switches 60 and 61 in or der to cal particular attention to the fact that these switches may be widely separated, if desired. The tank 10 may be supported in any convenient position and is. supplied with lubricant through the pipe 36, and with pressure by means of the pipe 38 which connects with any'suitablepressure supply. From the respective branch fittings 19 and 20, of the modified construction, extend feed pipes 62-6,3 and 64 65, which connect with any usualform of bearings as 66'66, and 67 of the shafts 68 and 69, which may be located at considerable distances apart, and may be associated with any ordinary form and construction ofmachinery to which it is customary to appl lubricant from time to time. Reference tot e drawings will clearly show that, upon the completion of the electric circuit by closing either of theiswitche's 60 or 61, the corresponding magnet 30 or 31 will be energized, and its related plate 24 or-25 will be attracted toward said magnet, thusopening the valve in one of the channels 17 or 18 and ICC permitting the lubricant to flow, under 'pressure, through the pi es 62-63, or 64-65, to the bearings with w 'ch said pipes communicate.

It is of course obvious that'any number of valved outlet connections may be supplied for each tank, and that each of the valves so supplied may be independently controlled by means of the electrically energized magnets herein shown, or through mechanical equivalents for said controlling devices.

It is evident that the construction of the several parts may be considerably varied from that shown in the drawings; and that some of the elements as, for instance, the shoes 48 and 49 may be omitted Without departing from the spirit of the invention.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent. 1. The combination with a truck having wheels adapted to travel on rails, of a tank mounted on sai truck, a valved outlet for said tank, control ing means for the valve located at a distance from said tank and delivery pipes connected with said outlet, one of said pipes being adapted to deliver lubricant to the main rail, and the other of said pipes being adapted to deliver lubricant to a guard flange of one of the rails.

2. The combination with a truck having Wheels adapted to travel on rails, of a tank mounted on said truck, a valved outlet for said tank, and a air of pipes connected to said outlet, one of said pipes extending to a point to deliver lubricant to one of the main rails and the other of said pipes extending to a point for discharging its contents on the guard flange of the other of said rails.

3. The combination with a truck having wheels adapted to travel on rails, of a tank mounted thereon, a plurality of valved outlets in said tank, means for actuating the valves independently, controlling means for said actuating means located at a distance from the tank, and pipes leading from said outlets respectively to points above the traction surface of one rail and above the guard flange of the other rail.

In testimony whereof I affix my signature in presence of two witnesses.
